Cooking with offal is one of the most rewarding ways to explore the whole animal. Rich, deeply savoury and surprisingly tender, beef heart is one of the most rewarding cuts to cook with. In this dish it’s seared quickly, then paired with a classic bourguignon-style sauce of smoked bacon, shallots, mushrooms and red wine. Served over buttery mashed potatoes, it’s a comforting and utterly delicious way to showcase this often-overlooked cut.
